February, 2003. Shoveling snow off roof tops in St.Anthony, Newfoundland Labrador

Students stranded by Newfoundland blizzard
Thu, 27 Feb 2003 from a CBC News Report

ST. ANTHONY, NFLD. - A severe blizzard pounding the northern peninsula of Newfoundland has stranded about 200 students at their schools. The heavy snow kept the buses from taking them home.

The snow has been so intense the plows have given up trying to clear the roads until it slows down. Drifts in some places have grown to three metres.

The storm came fast, said Merle Hoddinott, principal at Harriot Curtis Collegiate in St. Anthony. "Within 10 to 15 minutes, I'd say, we just couldn't see anything and the buses couldn't leave," he said.

Two buses trying to make the run home in St. Lunaire collided, and went back to the school.

Students camped out in schools in the region on Wednesday night, and might spend another night.

Hurricane Juan changes school year for some Nova Scotia Students- Sept. 2003

Students had a week off from school due to the hurricane. There were no classes at Halifax universities and schools, or in other parts of Nova Scotia, for the week of Sept. 29 to Oct. 3, 2003. Many schools were without power, had roofs blown off or sustained some other sorts of damage. Some students will have to be relocated for up to two months while repairs are carried out. Senior high students will have their semestered year adjusted.

Canadian Climate

Part of the Canadian mainland and most of the Arctic Archipelago fall within the Frigid Zone; the remainder of the country lies in the northern half of the North Temperate Zone. As a consequence, general climatic conditions range from the extreme cold characteristic of the Arctic regions to the moderate temperatures of more southerly latitudes. The Canadian climate is marked by wide regional variations. In the Maritime provinces (New Brunswick, Nova Scotia, and Prince Edward Island), extremes of winter cold and summer heat are modified by oceanic influences, which also cause considerable fog and precipitation. Along the western coast, which is under the influence of warm ocean currents and moisture-laden winds, mild summers and winters, high humidity, and abundant precipitation are characteristic. In the Cordilleran region the higher western slopes of certain uplifts, particularly the Selkirks and the Rockies, receive sizable amounts of rain and snow, but the eastern slopes and the central plateau region are extremely arid. A feature of the Cordilleran region is the chinook, a warm, dry westerly wind that substantially ameliorates winter conditions in the Rocky Mountain foothills and adjoining plains, often causing great daily changes.

Using graph paper, construct a line graph showing the average* temperature for each month.

* The mean or average temperature is calculated by taking the average of the high and low for each day of the month and then averaging that over the period of the data, in this example from 1961 to 1990. The temperature for January is not -5.8- that is just an historical average. The raw data charts at Environment Canada will show you the highs, lows etc. for each month. The data chosen for the graphs is representative of each province and territory, but you must keep in mind that other factors influence climate: nearness to large bodies of water, latitude,  and elevation. 

The graph has to have two vertical axis: the left shows temperature and the right shows precipitation.

Rain is measured in mm and snow in cm. Total precipitation changes snow to mm and adds it to the rain total. 

A bar graph shows precipitation.

After you have drawn the graph, ask yourself, " What does this graph teach me about the climate of this place ?" What can you conclude about the climate measured at the Halifax Airport ? You can also come to an understanding about climate by making comparisons between places in different regions. Compare Halifax with Yellowknife or Fredericton with Edmonton.
